a. Read pages 149-151. Write down the key concept on page 149. Write down the difference in an equation & function notation on page 150. Make note of the sidebar titled "Reading Math" on page 151, this will help you understand Example 4.
b. Watch the following video on Functions & write in your notes the example he gives after the whole food into Sal part - it's f(x) & g(x):
c. Do page 158 #1-11 (odd)
Answers: 1. no
3. yes; 3x-2y=25
5. 12; -24; the x-intercept 12 means that after 12 seconds, the scuba diver is at a depth of 0 meters, or at the surface. The y-intercept -24 means that a time 0, the scuba diver is at a depth of -24 meters, or 24 meters below sea level.
7. the graph goes up from left to right, goes through the origin, and has points such as (-1,-1) & (1,1)
9. the graph goes down from left to right, passes through the points (-3,0) & (0,-3)
11. The graph should be labeled "Rodeo Tickets". The y-axis is labeled "Number of adults" & the x-axis is labeled "number of children". Points should be at (0,6) & (12,0) with a line drawn connecting them.
The x-intercept 12 means that 12 children could attend the rodeo if there are 0 adults attending. The y-intercept 6 means that 6 adults & 0 children could attend the rodeo.
